Application filed. May 9, 1906. Serial No. 316,019.

To all whom it may concern:

Be it known that I, AIMii CLEMENT GRA- NEL, a citizen of the FrenchRepubhc, residing at St. Cloud, in the Province of Seinesheath ofgelatin or other suitable material,

that is to say, a material which will withstand the action ofhydrocarbons, and t con tains an absorbent and permeable llgneous bodysoaked with the hydrocarbon which it is desired to employ.

The cartridge or small carbureter is contained in the handle of theinstrument which may be ofmetal or other material which will withstandthe action of hydrocarbons, alcohol, ether and the like.

The accompanying drawing illustrates, by

wayof example, the application of the sys;

tem to a thermo-ca uterizer. V Figure 1 1s a vertlcal section of theinstrument; Fig. 2 is a longitudinal section of a modification of thesame; Fig.3 shows a carbureting cartridge detached in elevation; Fig.tis an elevation partly. in section of the cock of the saidmodification;and Fig 5 is a plan showing the arrangement which allows of turningtheplug'of this cook. a

The handle of the instrument consists of two parts: the bodyca-containing the carbureting cartridge Z) and the head 0 which carriesthe burner B.

The cartridge 2) introduced into the body a of the handle rests with oneof its ends upon a plug e of soft and permeablematerial forming acushion while allowing the air which is blown into the instrument tofilter through. i

The head 0 is provided with a shoulder f serving as a support for anindiarubber washer g which caps the other end of the cartridge and formsa hermetic joint between the body and the head of the handle of theinstrument.

pencil for pyrography, for ex- At the lower part of the body a is anozzle it provided with a cock 2', and which serves to receive the endof a tube connected with an air compressing bulb or other suitablecompressor.

The head a, which is separated from the body of the handle by theindiarubber washer 9, forms a chamber into which enters the carburetingair to be sent through a passage 1' to a passage 0 in a cock 7c, theplug of which is moreover provided with a passage m to which extends asmall tube at, the other end of which is connected with the interior ofthe body ('1 containing the carbureting cartridge.

.The two passages m and 0 in the plug of the cock is are bored at aright angle to one another so that according to. the position of thesaid plug its passages more or less uncover the tube j and the tube a atthe same time. I

The instrument is assembled in the following manner: The head 0 isunscrewed in order to uncover the upper mouth of the.

body a of the handle, and in this handle is placed the carburetingcartridge Z) previously perforated at each of its ends; it restswith'its lower'part upon the permeable plug 0, the head 0 is replaced inposition and the .indiarubber washer Q then caps the cartridge, forminga tight joint between the two compartments a and c of the handle;

the upper part of the cartridge projects into the upper compartmentformed by the head. Thecock- 7c beingin the proper position, air isblown in through the nozzle h, the air passes through the plug 6 andpart of it becomes compressed in the body of the handle while the otherpart passes through the cartridge as indicated by the arrows in Fig.1.

The air which is carbureted in its passage through the cartridge 6enters the head 0 of the handle and passes through the passageo 1n thecock, while the compresesd air in the lower part'or bodypasses throughthe tube a to the other passage m.

The carbureted air passing through 0 and the uncarbureted air whichpasses through m become mixed in the chamber 7) above the cook 70 andthence pass to the burner. It will be understood that according to theposition of the plug is the passages m and 0 will be moreor less open soas to allow of varying the proportions of the combustible mixture; thesepassages being at right angles to each other the proportions of carbureting and uncarbureting air vary inversely; a mixture of a givenrichness can therefore be obtained.

In the arrangement shown in Fig. 2 the mixture of carbureted andunearbureted air takes place in the cock itself and the eartridge ispressed towards its upper cap by a spring which insures a suflicientlytight joint for preventing the mixture of the air passing into thecartridge and the air passing around the said cartridge.

The head 0 is screwed on to the handle (1. and a milled flange (Z whichis provided on the head, not only serves as a stop to limit the movementof the head, but also serves in conjunction with the washer g, as aneffectual means for hermetically closing the joint between the cartridgewithin the bandle a, and the head. \Vithin this casing, at the lowerpart, is a cap 9 which is employed instead of the indiarubber washer orcap 9 of the preceding arrangement; this cap is of the same shape as theend of the cartridge 6 which is pressed against the cap by a spring rplaced in the lower part of the handle a. I prefer to interpose betweenthe spring 1', and the lower end of the cartridge 1), a cup 41, whichserves as a substantial retainer for that end of the cartridge. The cupis, of course, perforated to register with the open ing in thecartridge.

The head 0 is provided with the cock Z: which has only one passage 0.This passage 0 is enlarged at one end to allow of it comi'nunicatingwith the two passages j and 12, one for the carbureted air and the otherfor unearbureted air. By operating the plug by means of its forkedhandle 9 one of the passages j and n can be more or less opened, thusregulating the inlet of carbureted and uncarbureted air.

The head 0 is provided with an extension or stem 3 upon which is placeda socket 25 preferably of lignum vitae surmounted by several washers aof asbestos or other insu lating material held in position by means ofbolts 5 which bear upon washers 00, m

he washer 02 has an extension 1 in the form of a socket screw-threadedinternally to receive the burner.

It will be observed that the handle 9 which I? serves to operate thecock is is preferably in the form of a fork, the prongs of which areapplied (see Fig. against the two ends of the plug of the cock. On theside of smallest diameter (in this instance, tllU left-hand side of Fig.at) the prong of the fork serves, in conjunction with the screw .27, toprevent the plug from coming out of its shell.

heircompressed air is caused to enter through the nozzle 71 part of thesaid air passes into the cartridge whence it issues in a carburetedstate through the upper hole and the pa. The other part of thecompressed a 1' passes into the annular space provided between thecartridge and the handle and out through the passage 11.

The carbureted and uncmrbureted air thus become mixed in the passage 0ol the cock K. The admission of the (.zll'llllltlttl and unearburetedair is regulated by turning the plug of the cock by means of the handleQ and one of the passages or n, is more or less obstructed. Thecoinlnistible mixture thus reaches the passage 0 whence. it passes tothe burner.

For certain uses, particularly for luminous projections, and forsoldering lamps, oxygen instead of air may be passed into the apparatus.

Having now particularly described and ascertained the nature ()fl mysaid invention and in what manner the same is to be performed, I declarethat what I claim is:

l. A carbureting device comprising :1 casing with an outlet, a cartridgeinsertible in the casing and adapted to be pressed against said outletand having a passage adapted l'or comnumieation with the outlet when sopressed, and yielding means carried by the asing and engageable with thecartridge to hold the same pressed against said out let.

2. it carbureting device comprising a casing having a cap with anoutlet, a cartridge insertible in the casing, with one end adapted forinsertion within said cap and having a passage adapted for communicationwith the outlet, and a spring carried by the casing and engag able withthe other end of the cartridge, whereby it. held within the cap andpressed against the outlet therein.

In witness whereof I have hereunto signed my name this 26 day of April1906, in the presence of two subscribing witnesses.
